Abstract

An apparatus is provided, e.g. an optical transmitter, that includes an optical noise source and an optical coupler. The optical noise source is configured to produce light having a noise spectrum and is optically coupled to a selected one of the inputs. The optical noise conditioner is configured to receive the light from the optical noise source and to form a noise slice of the noise spectrum. The optical noise conditioner includes a wavelength blocker located in an optical path between the optical noise source and the optical coupler; and, an optical amplifier located in an optical path between the wavelength blocker and the optical coupler.
